－－Abstract Algebra Model and Ultrasonic Experimentation and Examination Cycle－－ (Optimization Techniques for Resonance Phenomena and Nonlinear Phenomena) The Ultrasonic System Research Institute has developed ultrasonic <dynamic control> technology that optimizes the interaction of ultrasonic vibrations based on various analytical results of ultrasonic propagation states obtained through an original ultrasonic system (sound pressure measurement analysis and oscillation control) using an abstract algebra model. Note: Control of resonance phenomena (low harmonics) and nonlinear phenomena (high harmonics) is achieved by setting oscillation control conditions based on a logical model. Compared to previous control technologies, this technique establishes and implements optimal control states tailored to the purposes of ultrasonic applications (cleaning, stirring, processing, etc.) through new measurement and evaluation parameters (note) concerning the entire propagation path of ultrasonic vibrations, including various propagation tools. This is a method and technology that can be applied immediately, and we are proposing and responding to it as a consulting service (there is an increasing track record in precision cleaning, stirring, and processing at the nano level). Note: Parameters: Power spectrum, autocorrelation, bispectrum, power contribution ratio, impulse response characteristics, and others.

The Ultrasonic System Research Institute has developed a new component inspection technology using megahertz ultrasonic oscillation based on its track record of analyzing ultrasonic data propagating on the surface of objects. This method applies the measurement and analysis technology of "sound pressure and vibration" through the control of original ultrasonic probe oscillation. We provide consulting and explanations of ultrasonic evaluation technology through the development of ultrasonic probes tailored to the purpose (vibration modes propagating on the surface of objects). This is an application of new ultrasonic oscillation control technology. By utilizing nonlinear phenomena related to megahertz ultrasonic propagation states that match the acoustic characteristics of the target object, it is possible to detect new features regarding the surface condition of the object. In particular, this fundamental technology serves as a new evaluation parameter for ultrasonic vibrations, utilized in surface inspection of substrate components and pre-evaluation of precision cleaning parts, leveraging the response characteristics derived from combinations of oscillation and reception. By measuring, analyzing, and evaluating the dynamic characteristics of ultrasonic waves related to the propagation phenomena of surface elastic waves, we have enabled effective use tailored to the purpose (evaluation) through the construction and modification of logical models.

The Ultrasonic System Research Institute has developed a technology to utilize (control) "nonlinear phenomena related to the generation of harmonics in ultrasound" by analyzing ultrasonic sound pressure measurement data (bispectral analysis, etc.) according to specific objectives. With this technology, when using multiple ultrasonic transducers with different frequencies, it becomes possible to set (manage) the propagation state of ultrasound influenced by harmonics. Therefore, it is possible to achieve appropriate or effective combinations of frequencies. This is very effective as it allows for the detection and confirmation of effective propagation states for cleaning, surface modification, and the promotion of chemical reactions. Furthermore, by combining the control of standing waves with the control of liquid circulation, dynamic control becomes possible to change the effects of cavitation and acceleration (acoustic flow) according to specific objectives. Through original measurement and analysis technology for ultrasonic propagation states, we have confirmed numerous effective cases related to the surface conditions of various components, including cleaning, stirring, surface modification, and chemical reactions.
